Regular Expressions with GLOB Module

-

 Regular Expressions with GLOB Module: -

  • The glob module in Python is used for pattern matching with file names and directories.
  • It works like wildcards in command-line shells.
  • It is not full regular expression, but it uses special symbols like *, ?, and [ ] for matching.
  • The glob module is a built-in module in python. If in case it is missing, we can install using

 

                                                Py -m pip install glob2.

 

  • To use glob( ) and its related functions, we need t import glob module. This function returns a list of all files matching a given pattern.

 1) Search exact string with glob( ): -

  • To search for a file with an exact name, just pass the filename.

            Example: -

            output: -


2) glob module with asterisk ( * ) wildcard: -

  • matches zero or more characters in file names.


            Example: -

            output: -


3) single character search with glob( ): -

  • single character ( ? ) matches exactly one character.


            Example: -


            output: -


4) multiple character search with glob( ): -  

  • [ ] matches any one character inside the brackets.


            Example: -

            output: -

v Operators: - An operator is a symbol that tells or intimates to the compiler to perform specific calculations or manipulations on one or more operands. Operators are essential for performing computations and making decisions in programs.   a + b is an operation a & b are operands + is an operator   Based on number of operands involved: 1.      Unary operators: - unary operators can be applied on only one operator. Example: -   ++ , -- , - (unary minus) , sizeof , ~ (compliment) , ! (not).   2.      Binary operators: - binary operators can be applied on two operands. Example: -   + , -,   * , / , etc.   3.    Ternary operators: - Ternary operator can be applied on three operands. Example: -   ?: (ternary conditional operator).   C supports several operators, can be classified into following...

Variables in c

  Variables: - A variable is a data name or an identifier which stores a value that can be changed during the program execution.  Every variable might belong to any of the data types, like int, float, char, etc.  The name of a variable can be composed of letters, digits, and the underscore character. It must begin with either a letter or an underscore.  Variables are case-sensitive because uppercase and lowercase letters are distinct. C programming language also allows defining various other types of variables, like numeric array, character array, pointer, Structure, Union, Enumeration and etc.               Example: - sum, height, _value Declaring a variable in C: - Variable declaration means telling the compiler about the name and type of a variable before using it in the program. Variable declaration is the process of reserving a memory location and defining the type of data that will be stored in that locatio...

  Cloud Storage and  Local Storage: Applications in Business: -   Local Storage: - Local storage refers to storing data such as text, audio, video, graphics, animation, special characters, constants, mathematical expressions and numeric data on physical devices in our computer or other electronic devices. Local storage in business refers to storing business data such as customer contact information, sales records, financial statements, employee data, market research, operational metrics, raw information like customer feedback.  It can also stores the structured data, such as in spreadsheets, or unstructured, like text from surveys or social media post on physical devices like hard drives, SSDs, or company servers within the organization’s premises.  The business owns and manages the storage hardware.  Local storage provides faster access to large files, which is helpful for tasks like video editing, 3D rendering, and engineering design projects. It o...
